FIREv EXTINGUISEER.

Application filed. March a,

This, invention relates to fireextinguishers. More particul'arly'stated, the invention relates t supports for the grenade type of fire extinguisher.-

This invention has for its salient object to provide a. support for a. grenade so construct'ed that the grenade can be easily and readily removed therefrom and, further more, so constructed and arranged that in 1 case of fire the grenade will automatically drop, break and dispense the fire extinguishingfluid; i j

I Another object; of the invention is to provide a bracket or holder for grenades com- 15 prising few parts and a structure that can be economically 'manufactured. 7

Further objects of' the invention will appear from the following specificationtaken in connection with. the drawings, whlch form 29 a part of'this application, and in which Fig. 1 is an elevation of a fire. extinguisher container; and support constructed in accordance with the 1nvent1on;

- Fig.2 is a top plan; view'ofthe construction shown in Fig- 1; I

4 Fig. 3is an elevational view partly broken, away showing the method of securingv the grenade supporting members to the bracket ,Fig. 4 is a sectional elevat on taken sub stantially on line offF-i'g. 3';

Fig. 5. is: a view: similar to. Fig. 1 showing another form oftheinvention; and, Fig. 6. is. a top plan view of the. device shown. in. Fig. 5;

The invention briefly described, consists of a fireextinguisher of the; grenade type and a; support therefor so constructed and ar 4 rangedzthat in caseof. fire the. frangible. contaiirer; or grenade; will berautomatically re: leased and will drop and break, thus free.- ing' the fire extinguishing liquid therein. I In the particular forms of the invention illus i-'5 t'rated, the frangible container is supported by an elastic or resilient ring, the ends of the ring being overlapped andheld in position by means-of a frangible bulb having therein afluidadapted to expand upona ris' '53 i'ng temperature and to explode the bulb.

Further details of'the invention will appear from the following description. In the form of the invention illustrated in.

the drawings, there is showna. back plate or bracket which is preferably formed of ametal' stamping, The bracket has ahole 11 adapted to receive securing; means for securing the plate to a support.

The plate 10 is indented, as. shown in liig .4:, at 12' and tabs 13 and 14. are punched outat the corners of the indented portion. The frangible container or grenade is sup ported in a resilient wire frame formedoff wire and having overlapping U-shaped end portions 21 and 22. Each U-shaped portion has, loops 2'5 adapted to receive the reduced ends 26- of a frangible. bulbQ/Z'. The bulb 27 formsav container for a suitable fluid or gas, such as carbon dioxide, which is adapted. to expand rapidly upona rise. in temperature and to explode the bulb.

p The wire cagecanbe formed by forming a I U-shaped. portion 21 intermediate the ends of a Wire, carrying: the. ends. as. shown at 30- and 31 around to form a curved or semi-cin. cular portion, passing the. ends through the lugs or tabs 13" and l, and forming another curved portion or a semi-circular portion. The ends are then, bent around to form the. other U-shapedportion 22 andtheloop 25...

As shown in-Fig. 1-,:the bulb 27'is inserted in position and the grenade or container 20 can bev placed imposition to. be supported by the. wire cage, this being, possible. because. of the resiliency of the. wire. If someone is present when the fire starts, the bulb: 20 can be grasped and pulled, from its. cage and thrown at. the fire-.1 However, if no one. is. present,; the rising temperature, due. to the fire; will: cause the. gas or fluidrwithin the bulb 27 to expand rapidly. and" explode the bulb. When thebulh explodes, the twocurved supporting portions ofthe. wire cage will sepfor securing the Wire cage. The outer ends of the flat band 34 are offset and are bent laterally to form lugs 35 and 36 having openings therein to receive the ends of the bulb 27. In this case the container 20 is supported on the upper edge of the band 34.

In case of fire the container can be grasped and thrown at the fire, provided some one is present, but in case no one is present the bulb will explode and release the container.

Although certain specific embodiments of the invention have been particularly shown and described, it will be understood that the invention is capable of modification and that changes in the construction and in the arrangement of the various cooperating parts may be made without departing from the spirit or scope of the invention, as expressed in the following claims.

What I claim is:
